create an equation to describe the relationship between the rise in temperature (y) and he change in time ( x) for the period from 6 to 24 minutes math connections

Answers

Answer 1

y = mx + b where m is the rate of change and b is the y-intercept, describes the linear relationship between rise in temperature (y) and change in time (x) from 6 to 24 minutes.

To calculate the linear equation, we can use the Point-Slope Form of a Line formula, y = mx + b. To find the slope (m), we must calculate the rise (change in the y-value) over the run (change in the x-value). We must calculate the temperature difference between 6 minutes (T1) and 24 minutes (T2). Then, divide the temperature difference by the time difference of 18 minutes. The y-intercept (b) can be found by plugging in the known x and y values of 6 minutes and T1 respectively into the equation y = mx + b. Once we have the slope and y-intercept, we can plug them into the equation y = mx + b to calculate the equation that describes the linear relationship between the rise in temperature (y) and change in time (x) from 6 to 24 minutes.

y = mx + b, where

m = (T2 - T1)/(24 - 6) = (T2 - T1)/18

b = T1 - (m*6)

Therefore,

y = (T2 - T1)/18 * x + (T1 - (m*6))

The given point is reflected across the line indicated. Find the coordinates of the image.
R across y = -2
If the given point R is reflected across the line y = -2, the image is
(Type an ordered pair.)

Answers

When a point is reflected across a line, the resulting image is always the same distance from the line as the original point, but on the opposite side. Since the original point R is above the line y = -2, the image will be below the line.

To find the coordinates of the image, we can use the fact that the y-coordinate of the image will be 2 units below the y-coordinate of the original point R. If the original point R has coordinates (x,y), then the image will have coordinates (x, y-2).

Therefore, the coordinates of the image of point R reflected across the line y = -2 are (x, y-2).

Answers

(a) After t years, the height is 18t² + 3t + 10

(b) The shrubs are847 cm tall when they are sold.

Claim: all natural numbers are either even or odd. Proof: By induction. Base case:0 is even, since 0 = 2.0. Now suppose that n - 1 is either even or odd, and we must show that n is either even or odd. Case 1: If n - 1 is even, then n - 1 = 2k for some k, so n = 2k + 1, showing n must be odd. Case 2: If n - 1 is odd, thenn - 1 = 2k +1 for some k, so n = 2k + 2 = 2(k+1), showing n must be even. Is this proof correct?
• Yes • No

Answers

No. The proof is wrong.

Here we are asked to prove all Natural numbers are either even or odd.

Natural numbers start from 1 to infinity.

Hence to prove by mathematical induction, we need to take the base case to be n = 1.

here, 1 = 2X0 + 1, therefore 1 is odd

Then we need to assume that for any integer m < n, m is either even or odd.

Now n > 1

Therefore,

n -1 > 0

Hence n - 1 will be a natural number.

Hence by our earlier assumption where any number smaller than is either even or odd

n - 1 has to be either even or odd.

case 1

here n - 1 is odd

if n - 1 is odd then

n-1 + 1 is a sum of two odd numbers, hence n is even

Case 2- If n - 1 is even

then, n-1 + 1 is a sum of an even and n odd number hence n is odd

Therefore n will either be even or odd.

2x ÷ 2 = 44 ÷ 2 (line 4)

x = 22 (line 5)

Kim’s error was in line 2 when she subtracted 6 instead of adding it. To cancel out -6, you would have to ADD 6, not subtract. So doing what Kim did would actually just make the problem 2x - 12 = 44, not have gotten rid of the -6.
If Kim had added 6 instead, she would’ve gotten

Diana
averages 6 mph walking
to school. Averaging 35 mph on
the way back home by car, she
takes 3/4 hour less time.
How far is the school
from her home?

Answers

The school is 5.43 miles from Diana's house. This is evaluated by using the speed-distance-time relationship.

What is the relation between the speed-distance-time?

The ratio of distance to time gives speed to an object.

I.e., S = D/T or D = ST ot T = D/S

Calculation:

It is given that,

Diana walks to her school at a speed of 6 mph.

So, the time taken for her to walk is t1 = d/6 hours

Diana returns home by car at a speed of 35 mph.

So, the time taken for her to return by car is t2 = d/35 hours

But it is given that, she takes 3/4 hours less time for returning by car.

Thus, we can write t2 = t1 - 3/4

⇒ d/35 = d/6 - 3/4

⇒ 3/4 = d/6 - d/35 = d(1/6 - 1/35)

⇒ 3/4 = d(29/210)

⇒ d = (3 × 210)/(4 × 29) = 5.431 miles

On rounding the obtained value to the nearest hundredths is 5.43 miles.

Thus, the distance between Diana's home and her school is 5.43 miles.

How to calculate compound interest?

You should be aware that compound interest is sum of money that accrues on the capital over a stated period of time.

The given parameters are:

Arianys investment = $61,000, interest rate 7% compounded continuously

Yusufs investment = $61,000, rate 7% compounded monthly

number of years each 14 years

Arianys investment

Compound interest = [tex]P(1+r)^{t}[/tex] - 1

Applying the figures we have

CI= 61000(1+0.07)¹⁴ - 1

=61000(1.07)¹⁴ -1

CI=$96,290.58

For Yusuf investment

CI=[tex]P(1+\frac{r}{n})^{nt} - 1[/tex]

Applying the figures we have

Ci=61000(1+0.0121)²⁹⁶⁸ -1

Compound Interest = 61000(1.0058)¹⁶⁸ - 1

Simplifying this we have

61000(164.36)

CI=$10,025,830.12

Therefore the amount in Yusufs account more than Arianys account is $(10,025,830.12-96,290.58)
